Seven months of heat, and winters that test the furnace you pick
From October through April your furnace is the thing standing between your house and a night that averages 26°F. That is seven months of run time a year, more than half the calendar, so whatever gets installed needs to hold up to steady use, not just the occasional cold snap.
Nearly half the homes in this area heat with gas, and any new gas furnace built since November 2015 has to reach at least 80 percent AFUE by federal rule. Storms are part of the picture too. Clark County has seen 9 winter storms and 79 damaging wind events over the past ten years, and statewide, 17 percent of households lost power for at least a day in 2024. A furnace installed here should be sized and set up by someone who understands what a long, hard winter and the outages that can come with it actually demand of it.

A high-efficiency gas furnace would save about $80 a year to run in Clark County compared with a gas furnace.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Indiana leaves this up to Clark County rather than testing contractors at the state level. So there is no state license behind the person doing this work, no record kept in Indianapolis, no test they had to pass to get one. Whatever protection exists here comes from what the county itself requires.
For a furnace install, that protection is usually the permit and inspection process. In most cities and counties, a furnace replacement needs a permit from the local building office and an inspection once the work is done, and that inspection is what catches a bad gas connection or a venting problem. Close to half the homes in Clark County heat with gas, so that check matters here.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and your ceiling height, so there is no single number that fits every house. A furnace that is too big will short cycle, heating your house in bursts and wearing out faster. One that is too small will run constantly and still not keep up on the coldest nights, and with winter lows here averaging 26°F, undersized is the mistake you feel the most. A contractor sizes it with a load calculation on your actual house, not a chart based on square footage alone.
- How do I know it's time to replace my furnace?
- Age is the first thing to look at. If a contractor has told you a repair costs a large share of what a new furnace would run, that is usually the point to stop repairing rather than keep patching an old one. Watch for signs too. Rooms that used to heat evenly now have cold spots, your burners cycle on and off more than they used to, or your gas bills have climbed without a reason. Homes here need heat from October through April, so a furnace on its last legs gets tested for seven months straight.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what furnace you have now. High-efficiency furnaces condense the exhaust to pull more heat out of the gas they burn, so less heat goes up the flue and more stays in your house. Any new non-weatherized gas furnace sold today has to hit at least 80 percent AFUE, and high-efficiency models are built to clear that by a wide margin. With close to half of homes here heating with gas and winter running seven months a year, the difference in gas use shows up on more bills than it would somewhere with a short season. A contractor can walk you through the actual models and what each one would cost installed.
